[PATCH v1 00/18] testing/next (tsan, dtc warnings, cross-builds)

["Alex Bennée" <alex.bennee@linaro.org>]

Hi,

This is the current testing/next queue. Aside from the minor bumps and
updates this returns --enable-tsan to the build.

This can help with debugging race conditions. You need a fairly recent
clang to enable it but configure will bug out if it can't be turned
on. Thanks to Robert Foley for picking up Emilio's work and getting it
through the review process.

There are a couple of minor testing updates including re-enabling the
cross-builds I disabled in the last PR I made as, predictably, Debian
finally pushed through the package update just as I turned the tests
off.

I hope to put together a PR on Tuesday.

The following are still missing reviews:

 - cirrus.yml: serialise make check
 - Revert ".shippable: temporaily disable some cross builds"
 - tests/docker: bump fedora to 32
